BHA Zirconia Resin Fiber Sanding Discs – 4.5 in x 7/8 in, 60 Grit, 25 Pack

Transform Your Finishing with BHA Zirconia Resin Fiber Discs

For projects that demand a smooth, controlled finish, these BHA Zirconia Resin Fiber Sanding Discs deliver a balanced blend of aggressiveness and precision. Each disc measures 4-1/2 inches in diameter with a 7/8 inch arbor hole, designed to fit most backing pads and standard angle grinders. The 60 grit grade offers a solid initial cut while maintaining edge control, helping you approach welds, edges, and transitions with confidence.

The durable zirconia resin fiber construction resists loading and maintains a consistent cut rate, so you can focus on shaping and finishing rather than constant disc changes. The pack includes 25 discs, providing a ready supply for extended jobs or multiple tasks without frequent restocking. This combination of size, grit, and material is well suited for a range of materials and finishes, from the first gentle skim to the final refinements.
